This invention relates to a machine for casting stereotype printingplates.

The objects of the invention are to provide means whereby a pair ofplates can be cast end to end in a horizontal casting box of a typesimilar to those now in use or a double truck plate can be cast thereinitdesired, or'either one of the single plate mold spaces can be used forcasting a single plate repeatedly without using the other. The inventionalso involves means for separating the flow of metal from a pump so asto deliver it to. the two mold spaces or to two widely separated pointsin a long thin mold space; improved means for sealing the lower edge ofa semipylindrical mold mounted at an incline, and for automaticallyopening said edge when it is desired to rotate the core out of the mold;simple means whereby the rotation of the core out of the mold and thenback into it will free the core from the plate and thendeliver the plateloose on the back of the core; simple improved means for stopping therotation of theshaft of the core after acomplete rotation is finished;means for automatically releasing the end rings from the cast plate andmatrix; means combined therewith for releasing the center rings when twoplates are cast, and other features if of the casting device cooperatingto produce either adouble truck plate or one or two single plates andautomatically deliver the same from the mold and get the mold ready forthe next cast; and also to provide improved'means for seating the castplate in the arch ready for shaving.

Other objects and advantages of the invention will appear hereinafter;

up into a firm seat in the arch and the shaving knife is commencing tooperate.

I have shown the machine in Fig. 1 with the casting part of it at theright and the shaving part at the left and illustrated the invention asapplied to a machine for casting and shaving a semi-cylindricalstereotype printing plate with the casting box in a position in whichits upper fiat side is on an incline, all supported on a frame 20.

Referring particularly to Figs. 1 and 5, the machine is operated througha belt on a pulley 21 which is fixed to a shaft 22. On this shaft is asliding clutch 23 for positively connecting the shaft with a worm 24which otherwise is free on the shaft. This worm drives a worm gear 25fixed on the main shaft 26 of the machine. The clutch is operated by alever 27 having a handle 28 and normally held in the position shown inFig. 5 by a spring 30. It swings on a stud 29. This lever is providedwith a projection 31 which during the rotation of the shaft 26 rests ona cylindrical guide 32 carried by the gear 25. his cylindrical guide 32has a notch 33. It will be understood that the spring is always tendingto pull the lever 27 over toward the shaft 26 and that whenever the gearrotates into such position that the projection 31 registers with thenotch 33, the lever will be swung over by the spring and the clutch 23disconnected. In this way the shaft 26 rotates through a completerevolution after being connected by pushing back the handle 28 and stopsautomatically at the end thereof without further attention.

The shaft 26 is mounted in bearings 35 arranged at suitable intervalsthroughout the machine. On this shaft is mounted the usualsemi-cylindrical water-cooled core and concentric with the shaft is theusual stationary semi-cylindrical concave water-cooled back 39. Theseare so arranged that when in the casting position shown in Figs. 5 and6, the plane of their top surface is at an incline shown in the drawingsas about but any convenient incline will do. In fact features of thisinvention will operate with a hori- Carried on the frame are supports orbearings 42 in which a longitudinal shaft 41 is located. This shaft hasa handle 44 at the end for turning it. It extends throughout the lengthof the casting box. It has keyed to it two arms 43 which engage acasting bar 45 extending throughout the length of the back at the lowerside and constituting means for closing the mold at that point with thehelp of certain features as will appear. These arms 43 are normallymoved upwardly to the position shown in Fig. 8 by springs and carry withthem the bar 45 which is adjustably connected to the arms 43.

- In getting ready for casting, the handle 44 5 has to be turned tobring these parts down to the position shown in Fig. 6. When that isdone, a pair of locking hooks 47 engage under a pair of projections 49at the two ends of the machine and are held there by springs 46 carriedby the bar 45. This construction holds these parts down in castingposition for the time being.

On the shaft 26 at both ends of the core there are cams 48 circularthroughout most of their peripheries and having one projection each. Atthe proper time these projections engage side projections on the hooks47 and swing these hooks back out of engagement with the projections 49.Now the springs 50 pull these arms 43 back to the position shown in Fig.8.

Connected with the shaft 41 are links 51 which at the other end engagecams 52 surrounding the shaft of the core at both ends. These camsoperating the links 51 control a pair of end rings 53. These end ringsare of usual semi-circular character projecting into the mold space andholding the edge of the matrix or matrices M. In the case illustrated inFig. 10 especially, they hold the opposite ends of two differentmatrices. Springs 54 normally pull these end rings back out ofmatrix-engaging position, but the cams 52 hold them in that positionduring part of the rotation of the core and at the time of casting. Whenreleased, they draw back and release the matrices at their 0ppositeends.

In Fig. 10 I have also shown two center rings 55 for engaging the innerends of the two matrices and closing the two mold spaces at that point.As shown at the left in this figure, each of these rings 55 is connectedwith the rod 56 by a collar construction 57 on the rod. The rod 56 isoperated by a lever 58 pivoted at the center and having its end oppositethe rod 56 connected by a link 59 with the adjacent end ring 53. Therefore when the end ring moves out as above indicated, the center ringmoves in by this simple construction. Of course, this arrangement isprovided at both ends of the core and two or more rods 56 andcorresponding parts are located at each end. The back itself is providedwith passages in which the rods 56 are located.

It might be stated at this point that in Figs. 14, 15 and 16 I haveshown a modification of this center ring arrangement in which both rings55 are formed with wedgelike projections and are held toward the matrixby means of a wedge segment 60. This is operated around the curvature ofthe box by the action of the gauge at the upper side of the mold, theconnections not being shown brings the upper gauge into contact with theprojections of the arch, .forcing it between ring 55 This can be usedwhere it is not considered necessary to loosen the inner edges of thematrix. In this case, the operator has to depend entirely on theloosening of the outer edges for preparing itfor ejection from thecasting box. I

In Fig. 13 a construction is shown for using the same back as in Fig.10for casting a single double-truck plate with a provisionat the centerfor using a single matrix. This is done. by removing the center ringsand substituting for them a filling ring 63 of the same curvature as thecasting box and filling whatever space there is to be filled at thispoint. The rod 56 can be removed or not but it is of course not usedwith this construction.

It is to be noted that there are two side bars 64, and 65, each. one ofwhich is adapted to come up against a stop 66. Each has aspring 67 forpushing it back against said stop and in a. recess therein.

each has an adjustable screw 68 which is mounted on a projection at itsback and at each end. As shown in Fig. 6, these two bars are'pushedforward toward the mold to cover a small portion of the edge of the moldspace by means of two cams 69 and 70. The cam 69 swings with the bar 45and the cam 70 swings with a shaft 71 which willbe referred to later.They are both pushed in together and pulled out together as willbe seenfrom from comparison of Figs. 6 and 8. It will be observed that the baris shaped to fit the 7 bar 65 at its edge and projects over it toformthe edge of the mold space-at that point, but

' even these two members do not extend clear across the space. The restof it is covered by a spring-pressed ejecting bar 72 which extendsradially from the core and is mounted These three-elements close thelower edgeof the casting space for casting purposes.

lVhen the shaft has turned to bring the core up out of the casting boxto the position shown in Fig. 7, the hooks 17 are just on the point ofbeing released by the cam 48. This allows the bar to rise to theposition shown in Fig. 8, taking with it'these hooks.

\ The cam 69 releases the bar so that the spring can move it backwardlyoutof' the way of the plate P which has been cast'in the mold. In thesame position, this bar 72 has engaged the plate P on the other side andas the core continues to rotate through another half of a revolution, itwill'eject the plate as shown in Fig. 8. The plate rests on the bar 72and a long projection 73 on the core. This leaves the plate exposed overthe core so that the matrix which is removed with it can be stripped offand the plate pushed into the shaving machine.

The method of introducing the metal into the mold is all old except asto one feature. The usual melting pot'75 is employed with a pump 7 6operated by a handle 7'7. This is provided with a discharge spout 78which is divided and delivers through twonozzles 79 spaced from eachother along the top of the mold space so as to deliver into both of themetal spaces of the mold separately. Where the spout divides, avalve ordeflectorSO is pivoted on a shaft 81 andoperated by a barn dle'82. Thishandle can be turned to three different positions as shown in Fig. 2 todeflect all the metal into either nozzle 79 or, when left in centralposition, to allowthe metal to flow out through both. This is to providefor casting single plates-at either end of the mold or a plate in eachend or a double truck plate extending throughout the mold.

The nozzle 79 delivers to the mold through a gate composed of twomembers 83 and 84 adapted to be swung about the bearings ofoperated forbreaking the riser R olf' the casting plate and delivering itoverbackwards as shown in Fig. 8.

Now the two plates are pushed out of'the position shown in Fig. 8 in alongitudinal direction overa pair of edge trimming saws 87 o'n-a shaft88, which-shaft'is operated by I a beltand pulley 89. The plates areguided one after the other along longitudinal'gu'ides 90for this purposeand theedg'es trimmed as is well understood.

The platesthen godirectly into the shaving arch 91 which is supported onthe frame 20. They run ona' stationary rail 92 at one:

side and a movable rail 93 at the other. When the plates have beenmoved" far enoughinto the arch, the operator swings a handle" 94 on ashaft 95. Through gearing 96 this turns a longitudinal shaft 97 whichhas cams 98 ateach end operating a' support 99 which is carried by arms100 pivoted on a longitudinal shaftlOl extending along the finishingarch. This action swings the plates upv into the arch and firmly seatsthem therein. Now the shaft 26- comes around while the next pair of,plates are beingejected' in accordance with the actions abovedescribed.The shaving blade 102 thereon shaves out the interior of both plates inthe usual manner. This blade is as long asthe core 40 so that itwillshave two single width plates or a double truck plate.

It will be seen therefore that while this machine is a complete castingand finishing machine involving the introduction of the metal into themold, cooling it, ejecting the cast plates, trimming the edges of theplates and shaving out the back, the principal features of the inventionrelate to the casting mechanism. These features have been fullydescribed in detail and the objects and operation already described infull. However, it may be stated that the operation of the castingmechanism without reference to the other parts is as follows: The handle28 is moved back from the position shown in Fig. 5 to close the clutch23. Then the projection 31 rests on the guide 32 as soon as the shaft 26is moved at all. The mold having been closed previously and the partsbeing in the position shown in Fig. 6, the first action is to turn thecore 40 from that position to the position shown in Fig. 7. This can bedone without moving any of the parts that keep the metal from flowingout of the mold at its bottom because the plate 72 is part of thismechanism and it moves backwardly with the core. Of course, the gate forintroducing the metal at the top has to be moved out of the way, whichis done in the manner indicated in the Jordhoy application abovereferred to. At the instant illustrated in Fig. 7, the cams 48 releasethe hooks 47 and the springs 50 turn the shaft 41 up to the positionshown in Fig. 8. This releases the edge plate so the spring pulls itback out of the way of the cast plate where it has previously remained.It should have been stated that in moving the gate for introducing themetal, the cam is moved out of contact with the I screw 68 and the upperedge plate 64 is also moved back by its spring. The shaft 26 continuesto turn and the plate 72 pushes the cast plates P and their matricesaround out of the casting box to the position shown in Fig. 8. The partsat the left occupy the position shown in that figure at the beginning ofthis movement and at its end. In the position shown in Fig. 8 the platesare ready to be pushed off either by hand or mechanically in alongitudinal direction on to the saws 87 and the rest of the operationis performed as previously described. 1

This forms a very simple machine for casting and finishing twostereotype printing plates or a double truck plate at each operation. Itis strong and durable and does not readily get out of order. 7 Eachoperation is automatic as the operator merely has to start the machineby means of the handle 28 and then has to pay no further attention tothat handle except to start it again. He also has to operate the handle44; once before each rotation for the purpose of bringing the bar 45down into closed position against the edge of the mold cavity and inopposition to the springs 50. He does this immediately after the platesare pushed off into the finishing apparatus. In the finishing machine,the handle 94 has to be operated to force the plates up into the arch,of course the handle 77 has to be operated to force the metal into themold and the upper gates have to be operated in the manner shown in Mr.Jordhoys application above identified.
